I just ordered my BW developing gear from B&H, along with 4x TMax 100...

Now the Question..
What is the difference between the using Xtol "Straight" or at different dilution as recommended by the Master Developer App.??

Like: Dynamic Range, Micro Contrast sharpness, Highlight detail, Shadow detail....

I shot a lot between 1pm and 4pm, so bright sun, deep shadows, bright highlights some times.

I am thinking of using ISO 50 with Xtol. But, I don't why, except maybe I think it will give better highlight detail.

Thanks ahead of time.
